Can't login after computer locks on idle

[Danilo Alculete]

After a leave my computer on idle and try to put my password to login the screen starts to blink whenever I click on the screen. The workaround I found is to click on the switch user button to log back in but some windows are closed on this process.
Also when the screen is locked I'm able to see the windows running on the user profile without unlocking

gnome-shell is responsible for the lock screen so reassigning to that

Yes it appears you still have animations disabled so like bug 1867967 this seems to be a duplicate of bug 1866044. To workaround the issue please enable animations for now.
